Solomon,Are you getting my requirement here now? Plz let me know if any doubts you have to under stand the question Probably with the Manifest class.

Create an object with an input stream from your manifest file. You can read the manifest file if you use the java. JarFile and than call getManifest. From than, use getMainAttributes. Sorry but can you clarify your question?

Do you have problem with accessing manifest file, or with parsing it? Also how does your code look like? Show 1 more comment. See Deploying with the Applet Tag for information on setting the permissions level in the applet tag. The Codebase attribute is used to restrict the code base of the JAR file to specific domains.

Use this attribute to prevent someone from re-deploying your application on another website for malicious purposes. Set this attribute to either the domain name or IP address where the JAR file for the application is located. The protocol and port number can also be included. For multiple locations, separate the values with a space. The following table shows sample values and what they match. If the attribute is not present, a warning is written to the Java Console and the code base specified for the applet tag or JNLP file is used.

A meaningful title helps users make the decision to trust and run the RIA. The value can be any valid string, for example:. If the RIA has an unsigned JNLP file or is started with the applet tag in a web page, use the Application-Name attribute to ensure that users are shown a valid title from a signed source. If neither attribute is present in the manifest, no title is shown in the security prompts.

The Application-Name attribute is ignored. If the files are not in the locations identified, the RIA is blocked. To specify more than one domain, separate the domains by a space, for example:.

If the Application-Library-Allowable-Codebase attribute is present and matches the location from which the RIA is started, then a single host is listed in the Location field for the prompt and the option to hide future prompts is provided. If this attribute is present and the files are accessed from a location not included for the attribute, then the RIA is blocked.

When multiple hosts are shown, the user can select the check box Do not show this again for apps from the publisher and location above. Use of this attribute is recommended so the files for the RIA are accessed only from known locations. The Caller-Allowable-Codebase attribute is used to identify the domains from which JavaScript code can make calls to your RIA without security prompts.

Set this attribute to the domain that hosts the JavaScript code. If a call is made from JavaScript code that is not located in a domain specified by the Caller-Allowable-Codebase attribute, the call is blocked.

If the Caller-Allowable-Codebase attribute is not present, calls from JavaScript code to your RIA show a security warning, and users have the choice to allow the call or block the call. Security prompts are shown for each Applet classLoader instance. See Codebase Attribute for a description of the values that are allowed. Users have the choice to allow the call or block the call.

An option to remember the choice is also provided. If the user chooses to remember the choice, no further warning messages are shown for the same RIA when it receives calls from JavaScript code from the same source. Change Language. Related Articles.
